Two Stable Heterometal?MOFs as Highly Efficient and Recyclable Catalysts in the CO2 Coupling Reaction with Aziridines

Two stable heterometal?MOFs, {Na[LnCo(DATP)2(Ac)(H2O)](NO3)?DMA?11H2O}n (Ln=Er(1) and Yb(2)), have been prepared and structurally characterized. They display excellent catalytic performances and recyclability in the CO2 fixation with aziridines into high?valued oxazolidinone.Two stable heterometal?organic frameworks, {Na[LnCo(DATP)2(Ac)(H2O)](NO3)?DMA?11?H2O}n (Ln=Er(1) and Yb(2)), have been prepared with H2DATP (4??(3,5?dicarboxyphenyl)?2,2?:6?,2????terpyridine) as organic building block. These two isostructural compounds featuring two?dimensional layer architectures possess outstanding thermal stabilities and excellent chemical stabilities in common organic solvents and different acid/base solutions with pH range changing from 1 to 13. Moreover, compounds 1 and 2 serving as heterogeneous catalysts can efficiently catalyse the CO2 fixation reaction with various aziridines to result in corresponding oxazolidinones at 70??C. Importantly, a good recyclable performance of 1 for at least 10 cycles is observed based on the experimental results, which are further confirmed by PXRD, TGA and ICP analyses.
